VENTILATING DEVICE Frank J, Scallon, Norwalk, Conn. Application April25, 1947, Serial' No. 743,974 y 2 Claims.

This invention relates to ventilation of the spaced with-in building wall, licor and roo-2 struetures and more particularlyto an improved rain and insect-excluding Ventilating device for Asuch spaces.

At present lit is not customary to provide ventilation for `the spaces ybetween raf-ters, stud ding members and floor joists of buildings, which spaces are Within the -rooffwal-l and `rlocr struc tures an-d are substantially closed, with the result that damp air leaking into suoli spaces deposits a-portion of its moisture therein and this `moisture tends-to accumulate lon -t-he structural members, walls, and insulating material ofthe building causing such serious` resultsas peeling or the paint, rotting of ythe jolsts, rai-ters and studdi-ng, deterioration of the plaster, warping of lloors, and similar results familiar to users of wood buildings. It is an object `ofthe present invention to pro- Vide adequate ventilation for such spaces so that any moisture deposited therein will be ltaken up and removed, and vto provide an improved ven- Ati-lating device-which will permit the freev flow of Ventilating air vthroughl such spaces While completely excluding the entry of rain or other precipitation, andvins'ects-theren. y

A somewhat more -sp'ecific object resides in the provision of an -improved Ventilating device for admitting air to relatively small spaces within building wall, roof and llo'or structures While fexcludingrain or. ctherprecipitation and insects from such places, which device is ysimple in construction, economical to manufacture, easy to install, and provides a neat and attractive appearance when installed in a building.

Other objects and advantages will become apparent from a -considerationof-the following description in conjunction with the accompanying drawings wherein:

Figure 1 is-a perspective View of a fragmentary portion of a-building showing the application thereto of Ventilating devices illustrative of the invention.

Figure 2 -is a transverse sectional view on an enlarged scale of a fragmentary portion of a building showing the application of the improved ventilating devices to the spaces between the floor joists of the building.

Figure 3 is a transverse sectional View of a r fragmentary portion of a building showing the application of the improved Ventilating devices to the eaves closure of the roof structure of the building.

Figure 4 is a front elevational View of an iml2 proved Ventilating device illustrative of the inven-tion, a portion of the front wall being broken away-to illustrate the application of the-insectexeludingsc'reen tothe structure; and

Fig-ure 5 is a transverse lsectional View on the line 5--5 olFigure 4.

With continued reference to the drawings, the house illustratedin Figures 1, -2 and A3', has walls it, a roof li, noors t2, as indicated in Figure 12, and an extension-provided with a fiat roof i3.

The housemay nir-'conventional construction and-thewa'l-lsmay include spaced studding members M carrying an outsideewalldcovering t5, and an inside covering it. The wall-s-tudding member-s are supported on floor joists il' which are in turn supported on a sill -Fl carried on a foundation t9. AThe spaces between the wall studs areclosed yat'tlfreir lower ends-by a supporting sil-120 and at their upper ends 4by a plate, not illustrated, arrdwtheffends of 'the spaces bei tween- -the -flo'or vjo'sts -Ifl-Y are closed by the other wall covering' t5, and vsuitable'lil-ler Ablocks 2 I.

The flat-roof portionfl may be constructed similar 'to the-floor lstru'cture with spaced Ajo'ists which carry the roof covering on their upper Vsurfaces and have aceiling covering attached to their liowers-urfaces, the en'fds ofthe spaces betweenthese roof juiste-being closed bythe endvwall covering of the' building'extension.

The roof M includes spaced vrafters r22 with the roo-fcovering y23 on the `upper edges thereof and an internal' wallbfcovering structure 24 underlying the rafters and Asecured to a portion of the lower edge of each rafter. Thef'lowerv ends of the spaces between the raf-'ters' are closed vby yan eaves-closure vmember 25, and the' upper ends -of these spaces open into-an attic space within the upper part of the roof which space is ventilated by suitable gable louvers, such as the -louver A2t shown in Figure 1.

The inner..vvaliy coverings Vvof ,the 4house are :preferably formed: :of or .provided ywith suitable insulating material and the floors .and .ceiling mayalso be insulated, ify desired.

Thespaces between the Aiioorjoists are lsuitably ventilated ,in .accordance with the present inventi'on providingfcircular.apertures 2B through the outer-wall covering. L5 ,and .through `the ller blocks' 2l, there bei gone .such .aperture :at .each end of each inter-joist space providing ventilating air passages into the spaces between the oor joists. The same method is used to provide ventilation of the spaces between the joists supporting the at roof portion I3.

The spaces between the rafters 22 are ventisages leading into the spaces between the wallstudding members, if desired. Each of vthese airpassage 'apertures has secured therein a rain and insect-excluding Ventilating devicefgenerally indicated at 30, and particularly illustrated in Figures 4 and 5.

The improved Ventilating device is preferably formed from a, single piece of thin non-corrosive material such as sheet aluminum or sheet copper. The mention of these materials, however, does not exclude the use of other suitable materials such as synthetic resin plastic, wood nbre, etc. The improved Ventilating device is simplel and economical in construction and comprises a cylindrical sleeve portion 3|, an end-wall 32 at one end of thevsleeve portion, and a circular screen 33 of vwire mesh positioned just inside of 'the end-wall 32. A marginal portion of the end-wall 32 extends somewhat beyond the cylindrical sleeve portion 3|, as indicated at 34, and the corresponding end of the sleeve portion is externally flanged at 35, the edge of this flange being integral with the outer edge of the endwall. This construction provides a doublewalled circular 4ange around the end of the sleeve portion to whichV the end-wall is attached, and the circular screen 33I has its outer circumferential portion clamped between the walls of this double-walled annular flange to permanently secureA the screen in operative position against the inner-side of the end-wall.

The end-wall is transversely slotted and has portions struck out to provide downwardlyinclined rain-excluding` I louvers v36, extending transversely across it. These louvers will effectively exclude theentrance of rain and other precipitation such aspsnow and sleet into the air passages leading to the. spaces in the building roof, floor and wall structure, and the screen 33 effectively excludes the entry of insects, air-borne material such as leaf fragments, and sparks into the spaces.l l f The cylindrical sleeve portion 3| is provided with spaced longitudinal notches or slots 31 which permit the sleeve portion to contract to a limited extent when it is forced into the outerend portion of an air-passage aperture in a building, and this sleeve portion is further provided with outwardly `projecting detents 38 between the slots 37 whichdetents engage the wall of the corresponding aperture to firmly secure the Ventilating devices in operative position in the building. The annular flange at the end-wall end of the cylindrical sleeve overlies the building surface at the outer end of the aperture receiving the Ventilating device and definitely positions the Ventilating device in the aperture 4 and provides a finished flange around the outer end of the device.

The use and advantages of the disclosed ventilating device are believed to be entirely obvious from the above description. It is also apparent that the device is neat and attractive in appearance, and does not, in any way, detract from the appearance of a building in which such ventilating devices are installed, and it is also apparent that' the devices. are s'ofr'si'rnple and;I economical in construction Athat the"advanta'gesprovided by them may be obtained without any appreciable increase in the cost of building construction.

What` is claimed is:

'1. A device for providing ventilation to the lspaces formed between the walls of buildings comprising a, cylindrical sleeve portion having circumferentially spaced longitudinal slots ad- .jacentone end thereof, said sleeve portion being provided with inclined detents disposed between said slots, an endwall formed integrally with the other end of saidl sleeve portion and provided With a plurality of transverselouvers, the peripheral edge ofi,hes leeve` portion adjacent said end wall being curved outwardly to form in conjunction with `the latter la double-'walled annular flange, and a circular wire mesh screen positioned withinsaidf other end of the sleeve portion and having its circumferential edge secured between the wallsV of said double-walled annular ange. 2.
